In 2016 Fairchild was acquired by ON Semiconductor (after 2022, onsemi). Fairchild Semiconductor International, Inc. was an American semiconductor company based in San Jose, California. Founded in 1957 as a division of Fairchild Camera and Instrument, it became a pioneer in the manufacturing of transistors and of integrated circuits. Schlumberger bought the firm in 1979 and sold it to National Semiconductor in 1987; Fairchild was spun off as an independent company again in 1997. In September 2016, Fairchild was acquired by ON Semiconductor. The company had locations in the United States at San Jose, California; San Rafael, California; South Portland, Maine; West Jordan, Utah; and Mountaintop, Pennsylvania. Outside the US it operated locations in Australia;[4] Singapore; Bucheon, South Korea; Penang, Malaysia; Suzhou, China; and Cebu, Philippines, among others.
